Sorry I didn't figure this out myself. Exel has two different random number generation formulas. One of them does not require the Analysis Toolpak, but the other does. My mistake...I thought that neither one of them required the Toolpak.

I'll be posting an updated version that fixes some problems in a couple of days...I'll include a Readme (and start a new thread so that I can quit hijacking this one.)
